Abstract

The development of increasingly sophisticated technology has made many changes and conveniences for humans in all things, including in the financial sector, cryptocurrency has emerged as a form of innovation in the world of finance. A cryptocurrency exchange is an electronic means for carrying out crypto asset trading transactions by sellers or buyers via websites or applications on mobile devices. Currently, many cryptocurrency exchange applications have poor service, security is not guaranteed, withdrawals take quite a long time, expensive admin fees, and other problems, so many Indonesians use reviews on Google Play Store to see user reviews before deciding to use the cryptocurrency exchange application. Many Indonesians are looking for information on cryptocurrency exchange applications that provide the best service for carrying out cryptocurrency buying and selling transactions. One of the cryptocurrency exchange applications that offers this is the Tokocrypto application based on reviews on the Google Play Store. This research aims to understand sentiment towards user reviews on the Tokocrypto application using the Naïve Bayes algorithm method for data classification. The data obtained is review data from February 2024, totaling 2000 reviews from the Google Play Store using Google Collaboratory. This research stage consists of data scraping using web scraping techniques, data labeling, preprocessing, TF-IDF weighting, implementation of the Naïve Bayes algorithm, and evaluation. The clean data obtained was 1000 with a total of 396 positive sentiments and 604 negative sentiments. The results of the sentiment analysis research using the Naïve Bayes algorithm method resulted in an accuracy level of 74.22%, precision of 63.25%, and recall of 81.40%.

Abstract

Digital transformation has become a major factor of change in various aspects of modern life, including business, education, and government. In the current era of digital transformation, the government is trying to improve efficiency and services to the community through the implementation of various technological innovations. The application of digital technology in public services is increasingly widespread, including in the administrative service sector such as the National Digital Samsat (SIGNAL) which allows people to make online vehicle tax payments through the SIGNAL application. User evaluations of this application can provide important insights for service providers. This research aims to analyze the sentiment of user reviews of the National Digital Samsat application on the Google Playstore platform using the Naïve Bayes algorithm. This method is used to classify user reviews into positive and negative sentiment categories. From 2000 reviews taken, 1,665 reviews were categorized as positive and 335 reviews as negative after manual labeling. Data preprocessing using RapidMiner includes cleaning, transform cases, tokenizing, stopword filter, token by length filter, and stemming. TF-IDF weighting is used to give weight to each word in the document. Evaluation of the Naïve Bayes model resulted in an accuracy of 63.61%, with 307 True Positives, 74 True Negatives, 26 False Positives, and 192 False Negatives. Precision was 92.19% and recall was 61.52%. The overall analysis shows that user reviews tend to be more positive towards the SIGNAL app, although there are some negative reviews. This conclusion gives an idea of users' positive perception of the app.

Abstract

The development of technology that occurs at this time is increasingly rapid, so it can be said to be an era of technological revolution where at this time almost all activities in society have used technology. One of the technologies that emerged in the current era of technological development is artificial intelligence(AI) technology. Artificial intelligence refers to the ability of computers to learn, adapt, and make decisions based on data. Currently, there are many artificial intelligence technologies in the form of applications that can be easily downloaded for free on the Google Play Store, one of which is the application resulting from the partnership between Microsoft and OpenAI, namely Bing Chat. The presence of Bing Chat as one of the artificial intelligence applications on the Google Play Store raises various user reviews while using the artificial intelligence technology. Based on this, a method is needed to analyze the various reviews on the Bing Chat application. This research aims to analyze user sentiment reviews of the Bing Chat application on the Google Play Store with the Naïve Bayes method. A total of 2000 user sentiment review data for the Bing Chat application on the Google Play Store in the January to February 2024 timeframe were collected using the web scrapping method. After going through the analysis process, 1877 sentiment data were obtained with 1653 positive sentiment data and 224 negative sentiment data. The evaluation results of this research on the sentiment of the Bing Chat application on the Google Play Store with the Naïve Bayes algorithm method get the results of the accuracy value of 67.16%, precision 93.53%, and recall 67.39%.
